What is polyaluminium chloride?

Polyaluminium Chloride (PAC) is an inorganic polymer coagulant. It is a yellow solid powder that is widely used in water treatments. PAC is better than other aluminum salts such as aluminium chloride, aluminium sulphate, and other various forms of Polyaluminium chlorisulfate and Polyaluminium chloride that they have lower charge than PAC.

What is polyaluminum chloride (PAC)?

Physical Details and Properties Polyaluminum Chloride (PAC) is a versatile chemical compound used in various industrial applications. It is an inorganic polymer with the chemical formula Aln (OH)mCl₃n-m, where n represents the degree of polymerization and m represents the number of hydroxyl groups.

How to manufacture polyaluminium chloride?

Method for manufacturing polyaluminium chloride with aluminum vanadine and calcium aluminate powder CN104671269A(en) 2015-06-03 Method for producing polyaluminum chloride from hydrogen chloride waste gas and aluminum salt water waste liquid generated from anthraquinone synthesizing production

Who makes polyaluminum chloride?

USALCO® has manufactured chemicals for over 60 years, and began full scale production of the patented process (US Patents 5,985,234; 5,997,838; 6,036,935 and Canadian Patent 2229266) for manufacturing Polyaluminum Chloride in 1996. USALCO manufactures a variety of Polyaluminum Chlorides to meet a wide range of water quality objectives.

How should polyaluminum chloride be handled?

When handling Polyaluminum Chloride, it is important to follow proper safety precautions: Handling and Storage: Store PAC in a cool, dry place away from incompatible substances. Follow the manufacturer’s guidelines for proper handling and storage. Health and Environmental Hazards: PAC should be handled with care.

How long does polyaluminium chloride take to precipitate?

Stable PAC needs at least 9 weeks at 30o to precipitate. The presence of water during the process will be evaporated in the reactor that produces steam. Finally, Polyalumunium chloride contains more than 50% Al2O3. Polyaluminium chloride is used in the treatment of drinking portable water and wastewater treatment.
